Logical Reasoning - Essential Part

1. Choose the word that is necessary for the word given in the question: Saddle

A. Horse

B. Seat

C. Stirrups

D. Horn


Answer : B. Seat


Explanation : 

A saddle is something one uses to sit on an animal, so it must have a seat (choice b). A saddle is often used on a horse (choice a), but it may be used on other animals. Stirrups (choice c) are often found on a saddle but may not be used. A horn (choice d) is found on Western saddles, but not English saddles, so it is not the essential element here.


2. Choose the word that is necessary for the word given in the question: Cell

A. Running

B. Swimming

C. Winning

D. Speaking


Answer : C. Winning

Explanation : 

Without a first-place win, there is no champion, so winning is essential. There may be champions in running, swimming, or speaking, but there are also champions in many other areas.


3. Choose the word that is necessary for the word given in the question: Glacier

A. Mountain

B. Winter

C. Prehistory

D. Ice


Answer : D. Ice


Explanation : 

A glacier is a large mass of ice and cannot exist without it. A glacier can move down a mountain, but it can also move across a valley or a plain, which rules out choice a. Glaciers exist in all seasons, which rules out choice b. There are many glaciers in the world today, which rules out choice c. 


4. Choose the word that is necessary for the word given in the question: Antique

A. Rarity

B. Artifact

C. Aged

D. Prehistoric


Answer : C. Aged


Explanation : 

An antique is something that belongs to, or was made in, an earlier period. It may or may not be a rarity (choice a), and it does not have to be an artifact, an object produced or shaped by human craft (choice b). An antique is old but does not have to be prehistoric (choice d).

5. Choose the word that is necessary for the word given in the question: Orchestra

A. Violin

B. Stage

C. Musician

D. Soloist


Answer : C. Musician


Explanation : 

An orchestra is a large group of musicians, so musicians are essential. Although many orchestras have violin sections, violins aren′t essential to an orchestra (choice a). Neither a stage (choice b) nor a soloist (choice d) is necessary.
